COFFEE-FLASK.

SPECIFICATION forming part of Letters Patent No. 511,780, dated January2, 1894.

Application filed June 6, 1892. Serial No, 435,692- No model.)

To all whom it may concern.-

Be it known that I, HIRsH KAPLAN, a citizen of the United States,residing at Baltimore, Maryland,have invented certain new and usefulImprovements in Coffee-Flasks; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawing, and to theletters of. reference marked thereon, which forms a part of thisspecification.

My invention has relation to pocket colfee flasks used by mechanics andartisans for carrying coffee, tea or other liquids, that are usuallyheated at the lunch or dinner hour, and the object is to provide asimple, cheap and non-explosive form of flask for this purpose as willbe hereinafter more fully described and particularly set forth in theclaim.

The figure in the drawing is a perspective view of my improved coffeeflask with a portion of the wall broken away to show the safety tube.

A is the flask proper and is provided with the ordinary screw cap B.

O is a U-sha-ped tube one end 0 of which projects a short distancethrough the top a, of the flask and communicates with the atmosphere.The other end 0' is beveled obtusely to the line of the tube, and issoldered to the side of the flask, with the beveled end in contact withthe under side of the top of the flask so as to leave a small air ventin said beveled end of the tube at the highest point in the top of thecan. The can being filled with the liquid, and the air tight cap screweddown, the whole may then be transported without danger of spilling evenshould the flask be carried in an inverted position, and should it benecessary to warm or heat the flask and contents at the noon or dinnerhour, it may be placed on astove or heater without unscrewing the cap,and left to itself, there mon form of flask, should the contents beheated while the cap is tight, as is frequently the case through thefailure or neglect of the user to loosen it. The beveled end 0' of thetube being located near the top prevents cofiee groundsor thelikegettingintothetube. The other end extending a short distance abovethe level of the top tends to prevent dirt or foreign matter-getting inwhile cleaning.

Having thus fully described myinvention, what I claim as new and useful,and desire to secure by Letters Patent of the United States, 1s

The combination with the body of the flask provided with afilling-and-discharge opening located centrally in its top portion andprovided with externally disposed screwthreads and a screw-cap, of thenearly U- shaped tube 0 having the open end of its longer arm projectingslightly above the outer surface of the top of the flask and permanentlysecured in the top of the flask, and having the shorter arm of saidtubeO beveled at its upper end and secured to the side Wall of the flaskwithin the body of the same and immediately below the top-wall of saidflask, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

I-IIRSH KAPLAN.
